IMPROVEMENT IN COAL'HODS.

Specification forming part of Letters Patent No. 160,873, dated March16, 1875; application filed March 1, 1875.

To all whom it may concern:

Be it known that I, EDWARD W. BYRN, of the city of Washington, intheDistrict of Golumbia, have invented a new and useful Improvement inCoal-Bods and I do declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this specification, in which-- Figure l is avertical front elevation; Fig. 2, a vertical section of Fig. 1 throughlineocm, and Fig. 3 a detail of the slide.

This invention relates to certain improvements in coal-hods and itconsists in the combination, with a coal-hod, of a reciprocating slide,the face of which is wrought into transverse forwardly-inclined ridges,which, after the manner of saw-teeth, slide under the coal durin g theretrograde movement, and urge the same forward with a positive motion onthe advance movement. It also consists, in combination with a coal-hod,of a rock-shaft, which terminates at one end in a handle for tilting thescuttle and operating the slide, and at the other in a crank forconverting the rotary motion into a rectilinear one. The inventionfurther consists in the combination of the rock-shaft, theconnecting-rod, and the reciprocating slide.

In the drawings, A represents the body of the coal-hod B, thesupporting-handle, and O the base-frame, which latteris made preferablya little deeper than usual, to allow plenty of room for the operation ofthe devices hereinafter described. D is the rock-shaft, which isjournaled in bearing-plates a, attached to the base-frame, and providedwith a handle, E, projecting from the rear of the hod, by means of whichthe hod is tilted and the said shaft is rocked. This said rock-shaft Dis held in position by collars b, in the place of which pins may beused, and terminates, at the end opposite the handle, in a short crank,F, which is attached to a connecting-rod, G, extending about half-way upthe hod. His a reciprocating slide, which moves in guideways c, andforms the bottom of the channel through which the coal is discharged.The said slide has its face wrought into transverse forwardly-inclinedridges, as shown in Fig. 3, which, like saw-teeth, slide under the coalwhen retracted, and delivers the coal with a positive motion whenadvanced. I is an extension attached to the under side of the slide H,which moves in a vertical slot, d, in the outer casing, and is attachedto the rod G in such a manner as to allow the latter a slight radialmotion. J is a lip or inner casing of sheet metal, extendingup over thelower end of the slide, for the purpose of relieving the slide of aportion of the superincumbent coal, and also for the purpose ofpreventing portions of the coal from obstructing the backward motion ofthe slide. This said casing may have at its lower end atransverse slot,to admit the removal of accumulated coal-dust.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with a coal-hod, of a reciprocating slide, havingits face wrought into transverse iorwardly-inclined ridges, which formthe bottom of the channel through which the coal is discharged,substantially as and for the purpose described.

2. The combination, with a coal-hod, of a rock-shaft having at one endahandle for tilting the hod and rocking the shaft, and at the other acrank for converting-the rotary into a rectilinear motion, substantiallyas described.

3. The rock-shaft D, provided with a suitable handle, in combinationwith the connecting-rod G and the reciprocating slide H, substantiallyas and for the purpose described.

This specification of my in vention signed by me this 27th day ofFebruary, A. D. 1875.

EDWARD W. BYRN.
